removing quotes



Hi, I want to print the list

L:[[1e-5,2e-5],[3e-5,4e-5]];

as a string with parentheses instead of brackets, decimal rather than
scientific
notation, and no quotes around the numbers. Like this :

(0.00001,0.00002),(0.00003,0.00004)

I played around with   printf, string, map   but have not been able to
obtain the desired result.

Thanks in advance for any help.
